The greenhouse effect refers to circumstances where the short wavelengths of visible light from the sun pass through a transparent medium and are absorbed, but the longer wavelengths of the infrared re-radiation from the heated objects are unable to pass through that medium.

The trapping of the long wavelength radiation leads to more heating and a higher resultant temperature. Besides the heating of an automobile by sunlight through the windshield and the namesake example of heating the greenhouse by sunlight passing through sealed, transparent windows, the greenhouse effect has been widely used to describe the trapping of excess heat by the rising concentration of carbon dioxide in the atmosphere. The carbon dioxide strongly absorbs infrared and does not allow as much of it to escape into space.

Solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface, which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse, but the way it retains heat is fundamentally different as a greenhouse works by reducing airflow, isolating the warm air inside the structure so that heat is not lost by convection.

If an ideal thermally conductive blackbody was the same distance from the Sun as the Earth is, it would have a temperature of about 5.3 °C. However, since the Earth reflects about 30% of the incoming sunlight, this idealized planet's effective temperature (the temperature of a blackbody that would emit the...

GLOBALWARMING POTENTIAL
Global-warming potential (GWP) is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide
FACTORS AFFECTING GLOBALWARMING
1.Carbon Dioxide Emitted from Cars
2.Burning fossil fuels
3.Cutting down the earth's forests without replanting
4.Releasing other greenhouse gases
5.The world's growing demand for electricity
ANTHROPOGENIC AND NATURAL CLIMATE CHANGE
Anthropogenic climate change is climate change that is due to the activities of human beings ( eg: burning fossil fuels, deforestation, etc.) While natural climate change is due to natural processes occurring on the Earth (such as dissolving of carbon dioxide in sea water and formation of carbonate rocks).

...GLOBALWARMING AND GREENHOUSEEFFECT – HOW CAN WE STOP THEM ?
The greenhouse effect occurs when certain gases in the atmosphere trap infrared radiation whereas
Globalwarming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect.
Burning fossil fuels raises the level of carbon dioxide in the atmosphere, and it is a major contributor to the greenhouse effect and globalwarming.
We can help to reduce the demand for fossil fuels, which in turn reduces globalwarming, by using energy more wisely.
The most important and useful way is Reduce, Reuse and Recycle.
We should do our part to reduce waste by choosing reusable products instead of disposables. Buying products with minimum packaging will help to reduce waste.
Planting more and more trees is another useful way by which we can control globalwarming and greenhouseeffect.
Because carbon dioxide is the most important greenhouse gas, planting trees and other plants can slow the rate of globalwarming. Plants take in carbon dioxide and release oxygen.
Another way is by reducing the use of fossil fuels.
To reduce the use of fossil fuels we should use less energy, or use...

Globalwarming -- a serious warning
I have a dream, that in a near future, the people of this world will come together as one. We could all come together as one and leave all our differences of color, religion, and political views behind us, to stand together to face what Bill McKibben calls the greatest challenge and threat mankind has ever faced: globalwarming. In 2007 Bill McKibben, an author, educator, and environmentalist, wrote the article, “Global Warning: Get Up! Stand Up!” to persuade people that we, the people on earth, have caused, and are still causing, the climate changes that have been taking place over the past decades. More than that, however, McKibben explains that something still needs to be done about it. McKibben uses extreme, yet reasonable, examples and methods to convey this message effectively.
Globalwarming is the result of the greenhouse effect, which has increased since the human race started to burn fossil fuels in order to extract energy. When fossil fuels are being burnt, greenhouse gasses, such as carbon dioxide, set free into the atmosphere. The accumulative pollution causes the atmosphere to reflect heat radiation back towards the earth, instead of letting the gasses disappear into space, because the ozone layer gets thicker. However, without the greenhouse...

...Is Greenhouse gases and globalwarming a real threat?
Human beings are about to encounter the worst catastrophe apart from the bubonic plague which characterized the middle ages. This threat is the globalwarming. So many people are still on the debate on whether globalwarming is taking place and also on the potential effects it has on the environment. However, most scientists and researchers are in agreement that, globalwarming is already taking place and it is going to increase uncontrollably in future. The world leaders have an option to view it as a real threat to the existence of man or decide to ignore it to the detrimental of the human race (Phil, par 1). Though some have doubted the existence of greenhouse gases and globalwarming, this essay shows that they are indeed reality.
Lately, the world has been characterized by so many debates on whether globalwarming is real or not, debate that does not exclude even the scientists. There are several facts that scientifically prove that globalwarming is real. These include several human activities that lead to emission of certain gases in the air, for example fuel burning. Burning of fuels such as coal and wood emit gases such as carbon...

The greenhouseeffect is happening right now at this very moment! According to our text book in physical geography; human induced burning fossil fuels such as natural gas, coal, oil and gasoline raises the level of carbon dioxide in the atmosphere, and carbon dioxide is a major contributor to the greenhouseeffect and globalwarming. (McKnight’s, Physical Geography, P.75, 2011)What will happen to the Earth and its people, animals, plants, lands and oceans if we fail to successfully address the environmental issues we face today? Our global population, air quality, human health, our food supply drinking water, wild life and habitats will all be effected with globalwarming. What can you do to preserve and protect the environment? There are many things we can do to help our mother earth. Opposition may be the large oil, auto, and coal companies and any explanation they may give from their studies will be bias.

...﻿The Greenhouse Effect
Rationale
The “Greenhouse Effect” is a term that refers to a physical property of the Earth's atmosphere. If the Earth had no atmosphere, its average surface temperature would be very low of about 18℃ rather than the comfortable 15℃ found today. The difference in temperature is due to a suite of gases called greenhouse gases which affect the overall energy balance of the Earth's system by absorbing infrared radiation. In its existing state, the Earth atmosphere system balances absorption of solar radiation by emission of infrared radiation to space (Climatological Information Service).
The greenhouse effect of the atmosphere has never been doubted. Most of the sun's radiation is visible light, which passes through the atmosphere largely undeterred. When the radiation strikes the earth, it warms the surface, which then radiates the heat as infrared radiation. However, atmospheric CO2, water vapor, and some other gases absorb the infrared radiation rather than allow it to pass undeterred through the atmosphere to space (Titus, J. G., et. al.).
A balance of naturally occurring gases dispersed in the atmosphere determines the Earth’s climate by trapping solar heat. This phenomenon is known as the greenhouse effect. As sunlight passes through our atmosphere, the incoming solar radiation is eradiated from the Earth’s surface as heat energy. Greenhouse gases trap some of this reradiated energy,...

...The Enhanced Greenhouse Effect
For the past ten thousand years the earth's climate has been extremely good and beneficial to mankind. Today however , major changes are taking place. Humans beings are changing the face of the entire planet by destroying the rain forests and pumping our pollutants into the air and water. Some of these gases are very toxic and they are destroying our ozone layers which allows life to exist on earth These things are changing the make-up of the earth's biosphere and its heat balance in a very negative way.
GlobalWarming is an increase in the earth's temperature due to the use of fossil fuels and other industrial processes, leading to a buildup of greenhouse gasses. It has been known that using these gasses stops the suns heat rays from getting into space.
This is called the greenhouseeffect. There is a question weather this adds to Co2 levels in the atmosphere. A rise in temperature could cause coastal folding and major climatic changes. This could have serious effects on agricultural productivity. Since 1850 there has been an average rise of 1 degree calculus (1.8 Fahrenheit). But this rise could be just a natural fluctuation or it could be from humans pumping fossil fuels into the atmosphere. It can be hard to tell if it is natural or man made, but either way, in 1995 it was the hottest year on...

...﻿Greenhouse gas
Greenhouse effect schematic showing energy flows between space, the atmosphere, and Earth's surface. Energy exchanges are expressed in watts per square meter (W/m2).
A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect.[1] The primary greenhouse gases in the Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. In the Solar System, the atmospheres of Venus, Mars, and Titan also contain gases that cause greenhouse effects. Greenhouse gases greatly affect the temperature of the Earth; without them, Earth's surface would average about 33 C° (59 F°) colder than the present average of 14 °C (57 °F).[2][3][4]
Since the beginning of the Industrial Revolution (taken as the year 1750), the burning of fossil fuels and extensive clearing of native forests has contributed to a 40% increase in the atmospheric concentration of carbon dioxide, from 280 to 392.6 parts-per-million (ppm) in 2012.[5][6] This increase has occurred despite the uptake of a large portion of the emissions by various natural "sinks" involved in the carbon cycle.[7][8] Anthropogenic carbon dioxide (CO2) emissions (i.e., emissions produced by human activities) come from combustion of carbon based fuels, principally wood, coal, oil, and natural gas.
